Answer:
16
Step-by-step explanation:
Let the number be A
From the question, if 7 is subtracted from half the number, absolute value of the result is equal to 1
This can be modeled by the expression below
1/2 A - 7 = 1
Add 7 to both sides of the expression
1/2 A - 7 + 7 = 1 + 7
1/2 A = 8
This can also be weritten as
A/2 = 8
Cross multiply
A = 2 x 8
A = 16
Put 16 for A in the expression above , the result is equal to 1.
Therefore,the number is 16
